The Eturnity Solar Calculator

Customer behaviour is shifting with advice and sales increasingly taking place online. Installers and energy suppliers face new challenges in offering online customer acquisition, initial consultation and the preparation of offers.
Subsequently, the Eturnity Solar Calculator is more than just an online calculator tool for those interested in solar energy systems. It is a digital assistant for new customer acquisition and lead management in the photovoltaic sector, working for you 24 hours a day.
It can be supplemented at any time with our PV planning tool – the Solar Expert.

The advantages of the Solar Calculator:

The Eturnity Solar Calculator can be integrated directly into your company’s website. It directly offers your potential customers the ability to find out more about their own photovoltaic system and storage possibilities online, as well as receive a cost estimate quickly. This makes the Solar Calculator a valuable tool for customer advice, also on the road or at trade fairs.

The Eturnity Solar Calculator guides your potential customers in an understandable, non-technical way through the simulation of their photovoltaic system. Users can select and mark their own roof using high-resolution satellite maps. Local electricity tariffs, your cost structure and the heating and domestic hot water system are taken into account in the cost estimate.

The Eturnity Solar Calculator is designed as a white label system. This means that it can be adapted to your company’s design according to your wishes and can therefore be consistent with your brand, making the Solar Calculator a suitable marketing tool.

The potential customers who use the Solar Calculator receive the data output directly as a PDF by e-mail on request. It assumes various roles in the initial consultation and also shows, among other things, what effects the subsequent installation of a battery has on the PV system. You can define up to three different battery systems, and the potential customer is suggested the most financially attractive system. You can access the detailed data of the Eturnity Solar Calculator and use it in your systems via an API connection.

NEW: Swisstopo map material

Now Swisstopo’s map material can be stored in the solar calculator. That means:

  • Swisstopo provides precise, up-to-date and reliable bases for surveying Switzerland, surveys the landscape and the subsoil and documents them over time
  • 5-part colour scale classifies the suitability of a pv system
  • The drawing of the roof surface is replaced by a click with Swisstopo
  • Swisstopo thus enables the automatic calculation of the roof area
